Ouch (and self-hosted atlassian products were pricy to begin with). Are there any good alternatives to Jira and Confluence out there (that are self-hosted/on-prem)?
This is why you hire dedicated Scrum Masters / PMO, and direct the PMOs to automate away what they can, as the domain becomes clearer.
Jira is actually really great for this because the REST API is so powerful, which can allow the PMOs to build systems which extract work from elsewhere, populate all the necessary fields which are repetitious and tedious for users to fill out, and then submit everything against the REST API and watch it all turn into issues.
When you start to understand that what Atlassian really did with Jira was build a powerful general UI abstraction over relational tables that even non-technical users can use, then you start to understand the sheer power of what's on the table.
